File "New", there's a dropbox at the top that needs changed to "Server", in the textbox put chat.nightscrawlers.com:6000, and change the dropbox next to that to "Open & Add to Favorites". Then, file "New", leave it on "Channel", put in #nightscrawlers, and "Open & Add to Favorites".

I give up. I can't get Trillian to connect to IRC, the connection keeps timing out, and all the other IRC clients I tried ask for a network, which our chat is not part of. So you'll see me again when java chat is running.
